Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technology, and in particular to a method, device and storage medium for receiving and sending uplink channel configuration information. Background Art

[0002] In wireless communication systems, such as 5G new radio (NR) communication systems, downlink data is carried on the physical downlink shared channel (PDSCH), and uplink data is carried on the physical uplink shared channel (PUSCH). The base station equipment schedules PDSCH and PUSCH through downlink control information (DCI) carried on the physical downlink control channel (PDCCH).

[0003] In the scenario where NR 52.6-71GHz corresponds to the unlicensed spectrum, the transmitter can follow the listen before talk (LBT) channel access mechanism on the unlicensed spectrum. In the LBT mechanism, the transmitter needs to monitor the channel to perform clear channel assessment (CCA). After CCA, the transmitter occupies the idle channel to send data, and cannot occupy the channel when it is not idle. The maximum channel occupy time (MCOT) that the transmitter occupies the channel is agreed upon by the protocol or configured / indicated by the base station.

[0004] In some scenarios, the transmitter may not need to perform LBT before sending data, but may perform contention exemption transmission (CET). How to determine whether CET can be performed on the uplink channel is a problem that needs to be solved.

[0107] The user equipment 101 shown above may be a user equipment (UE), a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent or a user equipment, etc. The user equipment 101 may have a wireless transceiver function, and it may communicate with one or more network devices of one or more communication systems (such as wireless communication) and receive network services provided by the network devices, and the network devices 102 here include but are not limited to the base station devices shown in the figure.

[0116] The embodiment of the present disclosure provides a method for transmitting uplink channel configuration information. Figure 2 , Figure 2 is a flowchart of a method for transmitting uplink channel configuration information according to an exemplary embodiment. Figure 2 As shown, this method includes:

The user device 101 receives the transmission mode indication information sent by the network device 102 and can determine whether it can perform contention-free transmission according to the transmission mode indication information. When the user device can perform contention-free transmission, the user device can directly occupy the channel to send data without using the listen-before-talk channel access method, so that messages can be sent more timely and communication efficiency can be improved.
